Just had Trans Fluid changed on a new to me 2005 HR scepter 44k miles, never change before, shop used synthetic ATF fluid, but not with TES 195 specs. Is this ok or is fluid TES 195 a requirement?

I don't have a DP, but at an Allison Transmission seminar I attended back in 2004 at an FMCA convention in Albuquerque, the technician stated that Allison teamed up with Castrol and developed Transynd transmission fluid.

He further stated if the new coach came with the Castrol Transynd fluid after the first 5,000 miles the primary filter needed to be changed and the amount of fluid loss replaced.

He said after that if the transmission wasn't equipped with a Retarder the next transmission service required was 150,000 miles. If the transmission had a Retarder service was required at 75,000 miles.

Not sure whether that still stands, but I would highly recommend you contact the Allison Transmission folks to best answer your question.

The advanced analysis kit will cover your needs and if you post the results here, Tom will interpret. The sad thing is, your transmission was filled with Transynd and the shop just filled with their product. The correct spec is TES295 not 195. If it's not one of Allison's approved TES295 fluids then the Allison schedule calls for fluid and filter replacement at 12 months.
